Description

Technical Field

[0001] This utility model belongs to the field of asphalt pavement paving technology, specifically relating to a permeable asphalt pavement paving device. Background Technology

[0002] Permeable asphalt pavement is widely used in urban road construction due to its good drainage performance and ecological benefits. The asphalt paving mechanism behind the paver uses an integrated feeding mechanism, screw conveyor mechanism and scraper to initially spread asphalt within the paving area. Currently, the bottom of the scraper of the paver is flat and the thickness of the asphalt pile is the same everywhere. However, in the actual paving process, when the press compacts the edge part of the asphalt pavement, "edge collapse" is prone to occur, causing some asphalt to be scattered outward. This results in a decrease in the actual effective asphalt paving amount at the edge, and the density of the asphalt pavement at the edge is 3%-5% lower than that in the middle. Due to insufficient compaction, the edge area is prone to longitudinal cracks, peeling and other damage under repeated vehicle loads. Utility Model Content

[0003] This invention provides a permeable asphalt pavement laying device that can improve the compaction of the asphalt at the edge by accumulating more asphalt and increasing the mutual compression strength of the asphalt after being compressed, thereby improving the strength of the asphalt pavement edge.

[0004] This utility model provides the following technical solution: a permeable asphalt pavement paving device, including an asphalt paving mechanism and a flat scraper, characterized in that: edge notches are provided at the bottom ends of both sides of the flat scraper, an upper extrusion plate is provided on one side of the edge notch, a joint flat paving plate is fixedly connected to one side of the upper extrusion plate, a side positioning baffle is fixedly connected to the other side of the upper extrusion plate, and an insertion sealing plate is provided on one side of the flat scraper.

[0005] Wherein, the length of the hypotenuse of the edge notch is greater than the length of the hypotenuse of the upper extrusion plate, and the side positioning baffle is a right trapezoid.

[0006] The upper extrusion plate has a clearance groove at its top, which matches the size of the insertion sealing plate.

[0007] The top of the joint flat paving board is fixedly connected to a connecting top plate, and the connecting top plate is fixedly connected to the flat paving scraper.

[0008] The top of the plug-in sealing plate is fixedly connected to a telescopic adjustment rod.

[0009] The telescopic adjustment rod is fixedly connected to a fixing block on its side wall, and the fixing block is fixedly connected to the side wall of the asphalt paving mechanism.

[0010] The side wall of the plug-in sealing plate is fixedly connected with an elastic protective gasket, which is in contact with the asphalt paving mechanism.

[0011] The beneficial effects of this utility model are: by setting an edge notch, asphalt with gradually increasing accumulation height can be set at the road edge. With the help of the extrusion plate, joint paving plate and side positioning baffle, the asphalt in the accumulation part is initially fixed. In the subsequent flattening process, with the help of more asphalt accumulation and the mutual extrusion strength of the asphalt after being compressed, the extrusion density of the asphalt in the edge part can be improved, thereby improving the strength of the asphalt pavement edge.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 The present invention provides the following technical solution: a permeable asphalt pavement paving device, comprising an asphalt paving mechanism 1 and a flat scraper 2, characterized in that: edge notches 21 are provided at the bottom ends of both sides of the flat scraper 2, an upper extrusion plate 3 is provided on one side of the edge notch 21, a joint flat scraper 31 is fixedly connected to one side of the upper extrusion plate 3, a side positioning baffle 32 is fixedly connected to the other side of the upper extrusion plate 3, and an insertion sealing plate 4 is provided on one side of the flat scraper 2.

[0019] In this implementation plan: When laying asphalt pavement at the edge, the telescopic adjustment rod 41 raises the plug-in sealing plate 4 located at the edge of the pavement, so that the edge notch 21 is open. The other plug-in sealing plate 4 remains flush with the bottom of the paving scraper 2. As the asphalt paving mechanism 1 and the paving scraper 2 move with the equipment, asphalt is laid and leaks out from the space below the paving scraper 2. Some asphalt is discharged outward from the edge notch 21 and then enters the space composed of the upper extrusion plate 3, the joint paving plate 31, and the side positioning baffle 32. The upper extrusion plate 3, the joint paving plate 31, and the side positioning baffle 32 work together to initially fix the asphalt that is higher than the rest of the pavement. It will not loosen and spread outward when the roller is not extruding. After the equipment moves, a flat center and sloping edges are left on the initially laid asphalt pavement. When the asphalt pavement is compacted by a road roller on the upward-convex road surface, the asphalt pavement at the edge is more compacted due to the increased asphalt accumulation. This increases the strength of the edge area of ​​the asphalt pavement. In actual operation, the edge area can be compacted multiple times to improve its density and smoothness. The upper extrusion plate 3 is located at the connection between the protruding and flat parts to achieve a smooth connection of the asphalt and prevent the edge of the upper extrusion plate 3 from leaving scratches on the flat asphalt part. When paving non-edge areas, the output shaft of the telescopic adjustment rod 41 extends, driving the plug-in sealing plate 4 to move down. When the telescopic adjustment rod 41 extends to its maximum distance, the bottom end of the plug-in sealing plate 4 is flush with the bottom end of the paving scraper 2 to achieve smooth paving of non-edge areas.

[0020] The length of the hypotenuse of the edge notch 21 is greater than the length of the hypotenuse of the upper extrusion plate 3, and the side positioning baffle 32 is a right trapezoid. The length of the hypotenuse of the upper extrusion plate 3 is longer, which makes the coverage length of the upper extrusion plate 3 longer, so as to completely cover the overflow periphery of the edge notch 21 and completely cover the asphalt discharged from the edge notch 21. The side positioning baffle 32 is a right trapezoid with the right angle side located on the lower horizontal plane. The upper hypotenuse gradually slopes outward and downward along the position close to the flat paving scraper 2, so as to gradually reduce the internal space formed by the upper extrusion plate 3, the joint flat paving plate 31 and the side positioning baffle 32, so as to initially extrude and fix the asphalt.

[0021] The top of the upper extrusion plate 3 is provided with a clearance groove 33, which matches the size of the insertion sealing plate 4. By setting the clearance groove 33, the insertion sealing plate 4 can be clearanced, so that the insertion sealing plate 4 can pass over the upper extrusion plate 3 and be inserted and sealed at the corresponding position of the edge notch 21. The size of the clearance groove 33 matches the size and position of the insertion sealing plate 4, so that the insertion sealing plate 4 can be accurately fitted and inserted into the clearance groove 33.

[0022] A connecting top plate 34 is fixedly connected to the top of the joint paving plate 31, and the connecting top plate 34 is fixedly connected to the paving scraper 2. By setting the connecting top plate 34, the joint paving plate 31 can be fixed, thereby reinforcing the upper extrusion plate 3 and improving the stability of the upper extrusion plate 3. In the actual installation process, the connecting top plate 34 can be fixed by bolt installation or welding. The side positioning baffle 32 is fixed to the asphalt paving mechanism 1 by welding. The joint paving plate 31 and the side positioning baffle 32 support the two sides of the upper extrusion plate 3 respectively, so as to achieve stable fixation of the upper extrusion plate 3.

[0023] The top of the plug-in sealing plate 4 is fixedly connected to a telescopic adjustment rod 41. The position of the plug-in sealing plate 4 can be adjusted by setting the telescopic adjustment rod 41. The telescopic adjustment rod 41 can be selected as an electric telescopic rod or a hydraulic telescopic rod according to the actual situation. The extension and retraction of the output shaft is controlled by the operator through the controller. The plug-in sealing plate 4 needs to withstand the pressure of asphalt. Each plug-in sealing plate 4 is supported by two telescopic adjustment rods 41. With the extrusion plate 3 limiting the plug-in sealing plate 4, the stability of the plug-in sealing plate 4 can be improved and the service life of this part can be extended.

[0024] A fixing block 42 is fixedly connected to the side wall of the telescopic adjustment rod 41. The fixing block 42 is fixedly connected to the side wall of the asphalt paving mechanism 1. By setting the fixing block 42, the telescopic adjustment rod 41 can be fixed, which facilitates the connection between the telescopic adjustment rod 41 and the asphalt paving mechanism 1.

[0025] An elastic protective pad 43 is fixedly connected to the side wall of the plug-in sealing plate 4. The elastic protective pad 43 is in contact with the asphalt paving mechanism 1. By setting the elastic protective pad 43, damage to the contact parts with the paving scraper 2 and the asphalt paving mechanism 1 can be reduced. When the inner side of the elastic protective pad 43 is in contact with asphalt and there is some residue, the elastic protection of the elastic protective pad 43 reduces the squeezing damage of the asphalt residue to the asphalt paving mechanism 1 and the side wall of the paving scraper 2.

[0026] The working principle and usage process of this utility model are as follows: When laying asphalt pavement at the edge, the insertion sealing plate 4 located at the edge of the pavement is raised upward by the telescopic adjustment rod 41 so that the edge notch 21 is in an open state. The other insertion sealing plate 4 remains flush with the bottom end of the paving scraper 2. As the asphalt paving mechanism 1 and the paving scraper 2 move with the equipment, asphalt is laid and leaked out from the space below the paving scraper 2. Some asphalt is discharged out through the edge notch 21 and then enters the space composed of the upper extrusion plate 3, the joint paving plate 31 and the side positioning baffle 32. In the process, the upper extrusion plate 3, the joint paving plate 31, and the side positioning baffle 32 work together to initially fix the asphalt that is higher than the rest of the road surface. It will not loosen and spread outward when the road roller is not extruding. After the equipment moves, a road surface with a flat center and sloping upward convex edges is left on the initially laid asphalt road surface. When the road roller is used to compact the asphalt road surface in the subsequent process, the asphalt road surface at the edge is compacted more densely due to the increased asphalt accumulation and the pressure of the horizontal roller of the road roller, thereby improving the strength of the edge part of the asphalt road surface.
